lf 前后端分离 (3) 中间建跨域

一.关于中间建跨域

为了减少跨域代码冗余,采用中间件

from django.utils.deprecation import MiddlewareMixin

class CorsMiddleware(MiddlewareMixin):

    def process_response(self,request,response):
        # 复杂跨域
        response["Access-Control-Allow-Headers"] = "*"
        # 简单跨域
        response["Access-Control-Allow-Origin"] = "*"
        # put请求 需要的跨域
        response["Access-Control-Allow-Methods"] = "*"

        return response
